Randomly accessible storage means for storing the digital audio signal supplied from the analog-to-digital conversion means; and a digital audio signal having the longest elapsed time since the digital audio signal supplied from the analog-to-digital conversion means was stored in the storage means. writing/reading means for temporarily stopping the operation of the reproducing means in response to a control signal supplied from the outside, and sequentially reading digital audio signals from the storage means in ascending order of elapsed time since storage at this point in time; and digital-to-analog converting means for converting the read digital audio signal supplied from the writing/reading means into a corresponding analog audio signal, and the analog audio signal supplied from the digital-to-analog converting means and the analog audio signal supplied from the reproducing means. and audio output means for outputting the analog audio signal as audio.

Embodiment Next, an embodiment of the present invention will be described with reference to the drawings.

FIG. 1 is a block diagram showing one embodiment of the present invention. The instant confirmation learning and playback device shown in Fig. 1 is a bilingual instant confirmation learning and playback device, and includes a signal control section 1 that generates control signals for internal control based on various externally applied signals, and a signal control section 1 that simultaneously records recorded content in two languages. A playback unit 2 that reproduces and outputs to channel 1 (CH1) and channel 2 (CH2), and a channel selection signal that is supplied in response to the output of channel 1 and channel 2 from the playback unit 2. a channel switching section 3 that supplies channel output to an analog-to-digital converter (hereinafter referred to as A-D converter) 4 and an audio output section 8; and A that receives the analog audio signal and converts it into a corresponding digital audio signal. - a D converter 4, a memory 7 that can be randomly accessed and stores a digital audio signal;
In response to the supply of a write start signal, the digital audio signals within a certain period of time are periodically rewritten in the memory 7 in the order of the stored contents starting from the earliest storage time. A memory control section 5 that reads out the contents stored in the memory 7, a digital-to-analog conversion section (hereinafter referred to as a DA conversion section) 6 that receives a digital audio signal and converts it into a corresponding analog audio signal, and a channel switching section 3. and an audio output section 8 which receives the audio signal from the DA converter 6 and outputs the audio signal.

Next, four input signals supplied to this embodiment will be explained.

"Two language switching signal" is a signal indicating which of the two languages the user has selected, and can be generated depending on the state of the channel selection switch.
Determine the channel to be stored in memory 7.

The "playback signal" is a signal generated when the playback switch is pressed during playback of recorded content, indicating that playback is in progress, and activates the playback section 7 and starts writing to the memory 7.

"Semantic confirmation signal" is the audio information of the channel selected by the user with the channel selection switch (e.g. English), and the audio information of other channels (e.g. Japanese).
This signal is generated by pressing a confirmation switch or the like when the user wishes to confirm the information, and the playback section 7 is temporarily stopped and reading from the memory 7 is started.

A "stop signal" is a signal generated by pressing a stop switch used to stop the device.

FIG. 2 shows a flowchart of this embodiment which operates in response to the various signals mentioned above.

The operation of this embodiment will be explained with reference to FIGS. 1 and 2.

Press the playback switch to generate a playback signal and enter playback mode. That is, the signal control section 1 sends a reproduction start signal to the reproduction section 2 in response to the supplied reproduction signal.
Then, a write start signal is supplied to the memory control unit 5, respectively.

The reproduction section 2 simultaneously reproduces the recording contents in the two languages, outputs them to channel 1 and channel 2, and supplies them to the channel switching section 3.

As an example, assume that channel 1 is English and channel 2 is Japanese, and the user is learning how to listen in English. In other words, let us consider a case where a user listens to English and then checks in Japanese on channel 2 to check the meaning of the message to see if he or she has understood it.

In the above example, channel 1 is selected by the channel selection switch, and a corresponding bilingual switching signal is generated and supplied to the signal control section 1. In response, the signal control section 1 supplies a channel selection signal to the channel switching section 3, and the channel switching section 3 supplies the English information output from the channel 1 to the audio output section 8, and the English information is output as audio. Output.

On the other hand, the channel switching section 3 supplies Japanese information, which is the output of the channel 2 not selected by the channel selection switch, to the A/D converting section 4.

The A-D converter 4 converts the supplied analog audio signal into a corresponding digital audio signal and supplies the digital audio signal to the memory controller 5.

Since the memory control section 5 has already been supplied with the write start signal, it temporarily stores the digital audio signal supplied from the A/D conversion section 4 in its internal buffer memory. A timing clock is separately supplied to the memory control section 5 at regular intervals, and the memory control section 5 transfers the digital audio signal temporarily stored in the buffer memory to the memory 7 in response to the supply of the timing clock.

Thus, while the user is listening to the English content of Channel 1, the Japanese content of Channel 2 is stored in the memory 7.

The writing operation to the memory 7 is performed by sequentially rewriting the stored contents having the longest elapsed time since they were stored in the memory 7 with the contents temporarily stored in the buffer memory. Therefore, the memory 7 always stores the contents of channel 2 that was reproduced within a certain period of time from the current point in time.

When the user presses the confirmation switch to confirm the meaning, a meaning confirmation signal is supplied to the signal control unit 1 which generates the meaning confirmation signal.

The signal control section 1 supplies a pause signal to the reproduction section 2 and a read start signal to the memory control section 5 in response to the supply of the meaning confirmation signal. The playback section 2 temporarily stops the playback operation in response to the supply of the pause signal. The memory control unit 5 interrupts the write operation by supplying the read start signal and starts the read operation of the stored contents from the memory 7. The read operation is performed on a first-in, first-out basis, that is, the data are read out in the order of the longest elapsed time since they were stored in the memory 7.

The digital audio signal read out from the memory 7 by the memory control unit 5 is supplied to the D-A converter 6 and converted into an analog audio signal, and the audio output unit 8 outputs the digital audio signal.
is supplied to

The audio output unit 8 outputs the analog audio signal (Japanese content in this case) supplied from the DA converter 6 as audio.

In this way, the user can hear the English content and immediately confirm it using the Japanese content, and can also read out the content of the memory 7 repeatedly in response to pressing the confirmation switch. To restart the device, simply press the playback switch again.

To stop the operation of this device, press the stop switch to generate a stop signal, and in response to the supply of this stop signal, the signal control section 1 sends a stop signal to the playback section 2 to stop the playback operation and control the memory. Part 5
It also stops the operation of.

In this embodiment, a two-language instant confirmation learning/playback device has been described, but the present invention is not limited to this, and can be used for instant repetition learning even when there is only one channel, and furthermore, even when there is only one channel, it can be used for two-way learning. It is also possible to store the two channels separately in memory so that both can be learned iteratively depending on the user's selection.

(Effects of the Invention) The present invention has the advantage that by accumulating the latest voice information in the memory and immediately outputting the accumulated content, it is possible to perform immediate confirmation learning and improve learning efficiency.
